Publication number: 20140150650Abstract: A gas-to-liquid heat exchanger is presented, where a gas is introduced directly to liquid. The liquid is exposed to the gas as a liquid film upon a series of rotating heat exchange surfaces partially submerged in a liquid reservoir. The liquid vaporizes and then re-condenses on subsequent heat exchange surfaces, such that heat is exchanged between the gas and the liquid. Particulates within the gas coalesce into the vaporized liquid and collect into the liquid reservoir as the vapor re-condenses.Type: ApplicationFiled: December 3, 2012Publication date: June 5, 2014Applicant: NEW ENGLAND WOOD PELLET LLCInventor: Steven J.

Patent number: 8534346Abstract: A modular, water-to-air heat exchanger with flexible tubes is adjustable in length to conform to different size cooling coils and thus provides an inexpensive, retro-fittable run-around heat recovery for pre-existing air handling systems. The heat exchanger comprises multiple heat exchange tubes formed of flexible material in a shape that permits them to be lengthened or shortened by simply moving the headers toward or away from each other. Preferably, the tubes are formed of a flexible, non-resilient material such as copper, and are shaped in a serpentine or helical manner. In this way, the tubes can be drawn out to elongate the heat exchanger or compressed to shorten it, depending on the dimension of the cooling coil in the air handler. One convenient way to control the length of the flexible tubes is to support the headers on one or more adjustment bars, each having a threaded adjustment mechanism.Type: GrantFiled: November 15, 2007Date of Patent: September 17, 2013Assignee: ClimateCraft Technologies, Inc.Inventor: Walter P.
